SPRAYlNG APPARATUS FOR MALT-FLOORS.

SPECIFICATION forming part of Letters Patent No.326,197, datedSeptember-15, 1885.

Application filed February 24,1885. (No model.) Patented in Germany May9, 1884, No. 29,293.

To all whom it Hwy concern.-

Beit known that I, OSCAR BOTHNER, of Lei psic, Germany, have invented anew and Improved Spraying Apparatus for Malt-Floors, of which thefollowing specification is a full, clear, and exact description.

This invention relates to means for throwing aspray upon malt during theflooring process. The spray is designed to prevent molding and tofacilitate proper germination.

To this effect the invention consists, principally, in the combinationof a carriage adapted to travel over the malting-floor with acompressed-air and a water tube, which eject a fin spray over the malt.

The invention also consists in the details of construction hereinaftermore fully pointed out.

' In the accompanying sheets of drawings,

Figure l is a side elevation, partly in section,

of my improved apparatus. Fig. II is a horizontal section on the line 00m, Fig. I; Fig. III, a vertical section on the line 3/ 3 Fig. I. Fig. 1Vis a side view of the apparatus on a reduced scale, showing it inoperation. Fig. V is alongitudinal vertical central section through amodification; Fig. VI, 9. side view of the same; Fig. VII, a top View ofthe same; and Fig. VIII, a horizontal section on the line a z, Fig. VI.Fig. lX is a side view on a reduced scale, showing this modification inoperation. Figs. X and XI are detail views of the drivinggear.

With special reference to Figs. I, IV, the letter A represents a railrunning above the floor from end to end and supported by uprights orhangers. This rail is somewhat inclined, and upon it travel the wheels Dof the spraying-carriage. This carriage is provided between its wheelswith a tube, E, connectedat one end to a compressed-air generator.

Within the tube E is inclosed the tube F, connected to a waterreservoir.The tube F is provided with lateral discharge-nozzles G, passing tightthrough the side of the tube E. The tube E is provided with small pipesG, bent in such a manner that the discharge-oped ings of said pipes Gcome in line with the discharge-openings of the nozzles G, so that thewater and air are ejected together and distributed upon the floor in theform of a fine spray.

In Figs. V, XI the apparatus is rotated as an reolipile, and ispropelled by such rotation. In these figures the rail B has anupwardlyprojecting shoulder, J, which is toothed on one edge, andengaged by a toothed wheel, J,

attached to the spray-carriage. The appara ms is provided with fourpipes, E, arranged at right angles to each other and provided withlateral dischargeopenings G. These pipes E are connected to a compressed-air generator. Within these pipes E the pipes F are arranged,connected to a water-reservoir, provided with lateral discharge-nozzlesG, the mouths of which come in line with the dischargeopenings G in thepipes E, whereby the water and air are ejected together and distributedin the form of a fine spray. At the same time the reaction of thisdischarge of water and air will operate the apparatus and turn the samearound its axis. In this modification the rail is not inclined.

The pipes are secured to the carriage in such a way that they may berevolved so as to turn the disehargeopenings to either the right or theleft side. The motion of the carriage is thus reversed by simplyreversing the position of the nozzles.

I claim as my invention 1. The combination of a carriage having wheelsI) with air-tube E and water-tube F, with discharge-nozzles G G,communicating near their discharge-openings, to discharge their contentsin the form of a spray, substantially as specified.

2. The combination of rails A with spray carriage having wheels D, andwith tubes E F, that'communicate near their nozzle, and with means forpropelling the carriage above the floor, substantially as specified.

3. The combination of rail B, having rack J, with spray-carriage havingtoothed wheel J, and with tubes E F and nozzles G G, substantially asspecified.

In testimony whereofI have signed my name to this specification in thepresence of two subscribing witnesses.
